Biomass and Bioenergy – After studies that resulted in ethanol from corn, sugar beet, cassava and traditionally sugar cane, the second sentence of students of power engineering course at PUC Minas fuel extracted from eucalyptus bark. They believe that this procedure will be adopted on a large scale in the country.
The same idea was also put forward by Julian Bragatto researcher, author of a doctoral thesis developed at the Escola Superior de Agricultura Luiz de Queiroz (Esalq), University of São Paulo (USP), in November 2011. At work, it showed that a ton of sugar cane produces about 80 liters of ethanol, while one ton of fresh bark of eucalyptus 106 produces, or at least 20% more.
The researcher also made a final statement pointing out that the fresh bark of eucalyptus would have an advantage of about 6% over the cane. In designing Bragatto the bark of eucalyptus soon begin to be used by the pulp industry for the production of ethanol and also to produce the bioplastic.
A little less confident is the specialist and creator of the Eucalyptus Online Book & Newsletter and Pinus Letter, Celso Foelkel. He says that the process can have good results, but in a long run. “Do not believe this to be viable in the short term, at least for the first generation ethanol. Already the second generation, only have a chance if the degradation of carbohydrates long chain were to occur via acid hydrolysis. Yet we have Difficulties in the bark as extractives, ash, lignin, “he says.
Amid concerns for fossil fuels and successive increases in the values of a liter of ethanol, studies and applications on the topic they are still an alternative. Therefore, the expectation, both for consumers – who complain of values as abusive to industry expert, is the best possible. “Science can solve mysteries. And new routes are always being created. Hopefully this [ethanol production from eucalyptus bark] is managed by staff of the PUC Minas Gerais,” concludes Celso Foelkel.
